Appeal No. 97-2909
Application No. 08/332,317
under 35 U.S.C. § 103 as unpatentable over Meulemans in view
of Bergman. As noted above, Meulemans discloses a light
source of the type claimed in which the cold regions of the
vitreous envelope are made of transparent, UV-absorbing quartz
glass, and the hot regions are made of normal (UV-permeable)
quartz glass. Bergman discloses the same type of light source
in which the vitreous envelope 16 may have a coating 42
consisting of alternating layers of tantalum oxide and silicon
dioxide or titanium oxide and silicon dioxide (col. 4, lines 2
to 6). This coating reflects infrared energy and also
"absorbs the ultraviolet energy of the lamp 16" (col. 4, lines
13 to 15). In view of this disclosure, it would have been
obvious to one of ordinary skill in the art to use Bergman’s
UV-absorbing coating on the lamp of Meulemans instead of the
UV-absorbing glass portions 2 of Meulemans, this being simply
the use of one known UV-absorbing means in place of another.
As for claim 15 et seq., it would have been obvious to provide
the Meulemans lamp with a reflector in view of Bergman’s
disclosure thereof.
We recognize that both in appellants’ specification (page
3, lines 20 to 27) and in their brief (page 6, lines 1 to 9),
